Deploy Astro on AWS

Deploy your Astro applications to AWS using Thunder patterns. This guide covers both static site deployment and full-stack server-side rendering options.

There are two deployment patterns available for Astro on AWS:

  1. Static Site — Deploy static Astro sites using S3 and CloudFront with the Single Page Application pattern
  2. Full Stack — Deploy SSR Astro applications using ECS Fargate with the Web Service pattern

Static Site Deployment

Deploy static Astro sites to S3 and CloudFront using the CDK-SPA library. This pattern is ideal for static sites, blogs, and client-side applications.

Create Project

Terminal window
npm create astro@latest my-astro-app
cd my-astro-app

Configure Astro for Static Output

astro.config.mjs
import { defineConfig } from 'astro/config';


export default defineConfig({
  output: 'static',
});

Install Dependencies and Setup Stack

Terminal window
npm i tsx @thunderso/cdk-spa --save-dev
stack/index.ts
import { Cdk, SPAStack, type SPAProps } from "@thunderso/cdk-spa";


const myApp: SPAProps = {
  env: {
    account: 'your-account-id',
    region: 'us-east-1'
  },
  application: 'your-application-id',
  service: 'your-service-id',
  environment: 'production',


  rootDir: '', // e.g. 'frontend/' for monorepos
  outputDir: 'dist/',
};


new SPAStack(
  new Cdk.App(),
  `${myApp.application}-${myApp.service}-${myApp.environment}-stack`,
  myApp
);

Environment Variables and Secrets for Build

Configure build-time environment variables using the buildProps configuration:

stack/index.ts
const myApp: SPAProps = {
  // ... other props


  buildProps: {
    environment: [
      { VITE_API_URL: 'https://api.example.com' },
      { VITE_ANALYTICS_ID: 'UA-XXXXXX' }
    ],
    secrets: [
      { key: 'API_KEY', resource: '/my-app/API_KEY' },
    ],
  },
};

Deploy

Build and deploy your static site:

Terminal window
npm run build
npx cdk deploy --all --app="npx tsx stack/index.ts"

After deployment, you’ll receive a CloudFront URL to access your static site.

For complete documentation, see the CDK-SPA README.

Full Stack Deployment

Deploy server-side rendered Astro applications using ECS Fargate and Application Load Balancer with the CDK-WebService library.

Configure Astro for SSR

astro.config.mjs
import { defineConfig } from 'astro/config';
import node from '@astrojs/node';


export default defineConfig({
  output: 'server',
  adapter: node({
    mode: 'standalone'
  }),
});

Install Dependencies and Setup Stack

Terminal window
npm i tsx @thunderso/cdk-webservice --save-dev
stack/index.ts
import { Cdk, WebServiceStack, type WebServiceProps } from "@thunderso/cdk-webservice";


const svcProps: WebServiceProps = {
  env: {
    account: 'your-account-id',
    region: 'us-west-2'
  },
  application: 'your-application-id',
  service: 'your-service-id',
  environment: 'production',


  rootDir: '', // e.g. 'app/' for monorepos
};


new WebServiceStack(
  new Cdk.App(),
  `${svcProps.application}-${svcProps.service}-${svcProps.environment}-stack`,
  svcProps
);

Build Settings Using Nixpacks

Configure automatic containerization with Nixpacks:

stack/index.ts
const svcProps: WebServiceProps = {
  // ... other props


  buildProps: {
    buildSystem: 'Nixpacks',
    installcmd: 'bun install',
    buildcmd: 'bun run build',
    startcmd: 'bun start',
  },
};

Build Settings Using Docker Container

Alternatively, use a custom Dockerfile:

Dockerfile
FROM public.ecr.aws/docker/library/alpine


# Install Bun
RUN curl -fsSL https://bun.sh/install | bash


# Update PATH for bun
ENV PATH="/root/.bun/bin:$PATH"


# Copy code, install and build
WORKDIR /app
COPY . .
RUN bun install
RUN bun run build


EXPOSE 4321
CMD ["bun", "start"]
stack/index.ts
const svcProps: WebServiceProps = {
  // ... other props


  serviceProps: {
    dockerFile: 'Dockerfile',
    port: 4321,
  },
};

Environment Variables and Secrets for SSR

Configure runtime environment variables and secrets:

stack/index.ts
const svcProps: WebServiceProps = {
  // ... other props


  serviceProps: {
    variables: [
      { NODE_ENV: 'production' },
      { PUBLIC_API_URL: 'https://api.example.com' }
    ],
    secrets: [
      {
        key: 'DATABASE_URL',
        resource: 'arn:aws:secretsmanager:us-west-2:123456789012:secret:/my-app/DATABASE_URL-abc123'
      },
    ],
  },
};

Deploy

Build and deploy your containerized application:

Terminal window
npm run build
npx cdk deploy --all --app="npx tsx stack/index.ts"

After deployment, you’ll receive an Application Load Balancer URL to access your SSR application.
